At the mo im in the first year of a levels and i was taking chemistry, biology, maths and physics. but physics really sucked as the teachers were always 15- 20 mins late, and the course is rubbish as its based in really life, so all the questions were like " in the mid 1880s american photographer Eadweard Muybridge took several sequences of photographs showing horses in motion. Treating the leg motion as a simple oscillation, state the phase relationships between the legs of a walking horse". That is an actual question i was given. ive now changed to further maths which i love but it is really hard especially as i have to catch up 1 1/2 months (about 40 hours) of work which i have missed... which leads me to my point: does anyone know of any good revision guides for OCR maths and further maths. Thanks liz xxxxxxxxxx ps any reassurance that i made the right decision to change from physics to further maths would be appreciated. i want to do medicine, so i wont be able to go to some universities now ive taken further maths, but i still think it was the right one to do. pps i do really like physics, i don't mean to offend any physicsy people by dropping the subject and saying it sucks. phsyics at my school sucks, not the cubject itself.
